S. Cass Weiland

Commercial Litigation

Cass is an accomplished commercial litigator and business lawyer who has served as lead counsel in civil cases involving contracts, securities, energy, construction and healthcare, as well as employment law and federal civil rights claims. He has counseled businesses on corporate and strategic issues, has represented companies of all sizes and has served as lead counsel for numerous Texas counties. Cass has handled arbitrations before the American Arbitration Association, the Federal Mediation and Conciliation Service and FINRA. He has mediated dozens of cases for his clients in many cities and served as a court-appointed mediator.

White Collar Criminal Defense

While counseling businesses and individuals embroiled in government controversies, Cass has represented clients accused of fraud, environmental crimes, tax offenses, antitrust and securities violations and a diverse range of other alleged misconduct. This practice often requires him to deal with a range of government agencies, from the Department of Justice (DOJ) and the Securities and Exchange Commission (SEC), to the Internal Revenue Service (IRS), the Food and Drug Administration (FDA), Departments of Defense (DOD), Agriculture and Health and Human Services, among others. He has also conducted internal investigations for public and private corporations, as well as corporate victims of fraudulent business schemes and improper employee conduct.

International Matters

Cass is frequently called on to handle legal issues involving controversies arising in whole or in part abroad. He has been retained to work on matters arising in the Middle East, the Caribbean and Central America. He is probably the only American lawyer to try a case before the 21 judges of the International Tribunal for the Law of the Sea in Hamburg. He has also traveled extensively in Europe on business-related matters.

Further enhancing Cass’ ability to deal with complex issues is his government experience, including serving as:

• Chief Counsel and Staff Director of the US Senate Permanent Subcommittee on Investigations (Washington DC)
• Trial Attorney in the Public Integrity Section, Criminal Division, Department of Justice (Washington DC)
• Assistant Director (Enforcement), Commodity Futures Trading Commission (Washington DC and New York City)
